2. Eligibility
This limited warranty applies only when all of the following conditions are met:
- The product is an eligible complete SYKERUNS bike whose product page states that this limited warranty applies.
- The product was purchased directly from sykerunsport.com or from a seller expressly authorized by SYKERUNS.
- The claimant is the original retail purchaser.
- Valid proof of purchase is provided.
- The product was assembled, used, charged, stored, and maintained in accordance with the applicable user manual and safety instructions.
This warranty is non-transferable unless applicable law requires otherwise.
No separate warranty registration is required for purchases made directly through sykerunsport.com. The official order record serves as the warranty registration.
3. Warranty Start Date
The warranty period begins on the date the original purchaser receives the product, based on the carrier delivery record or other reasonable proof of delivery.
A repaired or replacement product or component remains covered only for the remainder of the original warranty period. Repair or replacement does not restart or extend the original warranty period unless required by applicable law.
4. Covered Components and Warranty Periods
| Covered Component | Warranty Period | Coverage |
|---|---|---|
| Original frame | 2 years | Verified manufacturing defects in materials or workmanship. Cosmetic damage and damage caused by impact, overloading, stunts, racing, or misuse are excluded. |
| Motor system | 1 year | Verified manufacturing defects in the original motor under normal, intended use. |
| Battery pack and battery management system | 1 year | Verified manufacturing defects. Normal capacity reduction, range variation, and damage caused by improper charging or storage are excluded. |
| Controller, throttle, wiring harness, and original electrical controls | 1 year | Verified manufacturing defects under normal, intended use. Water intrusion, damaged connectors, and unauthorized electrical modifications are excluded. |
| Display, lights, and original switches | 1 year | Verified manufacturing defects under normal, intended use. Impact, water damage, and broken screens caused by external force are excluded. |
| Original charger | 1 year | Verified manufacturing defects when used with the specified SYKERUNS battery and in accordance with the user manual. |
| Suspension system, including original front fork and rear shock | 1 year | Verified manufacturing defects. Routine adjustment, seal wear, lubrication, leakage caused by impact, corrosion, or misuse are excluded. |
| Braking system, including original calipers, master cylinders, and hydraulic lines | 1 year | Verified manufacturing defects. Brake pads, normal rotor wear, fluid replacement, adjustment, and damage caused by impact or improper maintenance are excluded. |
| Other original mechanical components, when equipped | 1 year | Verified manufacturing defects in the original fork components, stem, handlebar, headset, seat post, rims, wheel hubs, crankset, pedals, sprockets, shifter, derailleur, and similar installed components. Normal wear is excluded. |
Only the original components supplied with the eligible complete bike are covered. Separately purchased parts or accessories are covered only when their product page provides a separate written warranty.
5. What Is a Covered Manufacturing Defect?
A covered manufacturing defect is a verified failure in material or workmanship that prevents an original covered component from functioning as designed during the applicable warranty period under normal, intended use.
Examples may include:
- A covered electrical component that fails because of a verified factory defect.
- A structural frame defect caused by defective materials or workmanship.
- A covered motor, controller, display, charger, suspension, or brake component that does not function as designed because of a verified manufacturing defect.
- A battery pack or battery management system failure caused by a verified manufacturing defect.
The existence of a problem does not automatically establish a manufacturing defect. SYKERUNS may require photographs, videos, serial numbers, diagnostic information, test results, maintenance information, or physical inspection before approving a warranty remedy.
6. Battery Warranty Conditions and Exclusions
The battery warranty covers verified manufacturing defects in the original battery pack and battery management system during the applicable 1-year warranty period.
The following are not considered manufacturing defects:
- Gradual reduction in battery capacity caused by normal aging or use.
- Reduced range caused by rider weight, cargo, terrain, riding mode, speed, tire pressure, temperature, wind, storage conditions, or normal battery aging.
- Damage caused by a third-party, incompatible, or incorrect charger.
- Damage caused by deep discharge, prolonged storage without maintenance charging, improper voltage, power surge, extreme temperatures, impact, puncture, corrosion, water intrusion, or misuse.
- A broken, removed, altered, or tampered battery seal.
- Use of the battery in a product or model for which it was not designed.
- Opening, modifying, disassembling, or attempting an unauthorized repair of the battery.
- Failure to follow the charging, storage, and safety instructions in the applicable user manual.
Stop using the battery and contact SYKERUNS immediately if it shows swelling, leakage, unusual heat, odor, smoke, physical damage, or other abnormal behavior.
7. Normal Wear and Maintenance Items
This warranty does not cover normal wear, routine adjustment, consumable items, or scheduled maintenance.
Normal wear and maintenance items include, but are not limited to:
- Tires and inner tubes
- Brake pads and brake rotors worn through normal use
- Chains, sprockets, chainrings, belts, cassettes, and drivetrain wear
- Bearings, bushings, seals, cables, hydraulic fluid, and fasteners subject to normal wear
- Grips, seats, pedals, foot pegs, and cosmetic trim
- Paint, decals, finishes, and surface appearance affected by normal use
- Bulbs, reflectors, and other consumable or replaceable items
- Routine brake, suspension, wheel, chain, and steering adjustment
A manufacturing defect in a normally wearable component may still be considered when supported by evidence and confirmed by SYKERUNS.
8. General Warranty Exclusions
This limited warranty does not cover damage, failure, or loss caused by:
- Accident, collision, impact, crash, dropping, overturning, fire, theft, vandalism, or external force.
- Misuse, abuse, racing, competitive use, rental use, commercial fleet use, stunts, jumping, overloading, or use outside the product's intended purpose.
- Improper assembly, installation, adjustment, repair, service, or maintenance.
- Failure to follow the user manual, safety warnings, charging instructions, maintenance requirements, or applicable laws.
- Unauthorized modification of the frame, electrical system, speed settings, battery, controller, motor, wiring, brakes, suspension, or other components.
- Use of incompatible parts, batteries, chargers, accessories, software, or electrical components when the incompatibility caused or contributed to the failure.
- Water immersion, flooding, pressure washing, corrosion, salt exposure, chemical exposure, or environmental exposure beyond the product's stated design limitations.
- Improper storage, prolonged exposure to extreme heat or cold, neglected maintenance, or failure to maintain battery charge during storage.
- Cosmetic deterioration, scratches, dents, fading, discoloration, surface rust, minor noise, minor vibration, or finish variations that do not affect safe operation.
- Damage caused by customer-arranged shipping, freight forwarding, third-party forwarding, or inadequate return packaging.
- Products with removed, altered, damaged, or unreadable serial numbers or identification labels when the alteration prevents reasonable verification.
- Products purchased from unauthorized sellers, private resellers, liquidation channels, auctions, or secondhand marketplaces.
The use of a third-party part or independent repair service does not automatically void the entire warranty. However, damage caused by an incompatible part, improper service, or unauthorized modification is not covered.
9. Accessories, Gifts, and Separately Purchased Parts
This warranty applies to eligible complete bikes and the original covered components listed in Section 4.
Unless a separate written warranty is clearly stated on the applicable product page, the following are not covered by this limited bike warranty:
- Riding gear and apparel
- Bags, keychains, stickers, cosmetic accessories, and decorative parts
- Free gifts, promotional items, and giveaway products
- Replacement parts purchased separately
- Third-party accessories or components
If a separately purchased official component includes its own written warranty, that separate warranty controls.
10. Shipping Damage
Shipping damage is handled under the SYKERUNS Shipping & Delivery Policy and Return & Refund Policy rather than as a later-arising manufacturing defect.
If a product arrives damaged, defective, incomplete, or incorrect, contact support@sykerunsport.com within 7 days of delivery and provide the order number, tracking number, clear photos or videos, and images of the outer carton, inner packaging, and shipping label.
If shipping damage or an incorrect shipment is confirmed, SYKERUNS will provide an appropriate approved solution without charging the customer the approved return shipping cost.
11. How to Submit a Warranty Claim
To submit a warranty claim, contact support@sykerunsport.com and provide:
- Order number and proof of purchase
- Product model and serial number
- Date the issue was first noticed
- A clear description of the issue and the circumstances in which it occurs
- Clear photographs and videos showing the product, affected component, and issue
- Any diagnostic information reasonably requested by SYKERUNS
- Current shipping address and contact information
Warranty claims should be submitted within a reasonable time after the issue is discovered and before the applicable component warranty period expires.
Our support team generally responds within 1–2 business days. After all requested information is received, the claim is generally reviewed within 3–5 business days. Complex diagnostics, parts availability, carrier investigations, or physical inspection may require additional time.
12. Diagnosis and Authorization
SYKERUNS may use photographs, videos, remote troubleshooting, electrical readings, component testing, serial-number verification, maintenance information, or physical inspection to determine whether an issue is covered.
Customers must follow reasonable diagnostic and safety instructions. Do not continue riding or charging a product that may be unsafe.
Do not ship a complete bike, battery, or component without written authorization. The authorized warranty return address may be different from the original shipping address.
If an item is sent without authorization, to an incorrect address, or without the required packaging, the shipment may be delayed or refused. SYKERUNS does not charge a separate unauthorized-return handling or restocking fee, but the customer may remain responsible for loss or damage caused by unauthorized shipping or inadequate packaging.
13. Available Warranty Remedies
If SYKERUNS confirms a covered manufacturing defect, SYKERUNS will provide an appropriate remedy, subject to applicable law. Depending on the circumstances, the remedy may include:
- Remote troubleshooting or adjustment guidance
- Repair instructions
- Replacement of the defective component
- Authorized repair
- Replacement with the same or a reasonably equivalent product
- A refund when repair or replacement is not reasonably available
SYKERUNS may use new or functionally equivalent replacement components that meet the required performance and safety standards.
Most approved warranty replacement parts are arranged within approximately 3–10 business days after claim approval, subject to parts availability, carrier scheduling, and shipping conditions.
14. Warranty Shipping and Labor
For an approved warranty claim involving a verified covered defect, SYKERUNS will cover reasonable shipping costs that SYKERUNS authorizes in writing for replacement parts or an approved return.
Customers must use the shipping method, label, return address, and packaging instructions provided by SYKERUNS. Unauthorized shipping costs are not reimbursable unless required by applicable law.
Unless SYKERUNS authorizes the service in writing or applicable law requires otherwise, this warranty does not cover:
- Third-party labor charges
- Diagnostic fees charged by an outside repair provider
- Removal or installation labor
- Travel, pickup, delivery, or mobile repair fees
- Loss of use, rental costs, missed work, or inconvenience
15. Safety-Related Claims
Stop using the product immediately if the issue may affect safe operation, including unusual braking behavior, structural damage, exposed wiring, battery swelling, overheating, smoke, burning odor, or abnormal electrical behavior.
Move the product away from flammable materials when safe to do so and contact SYKERUNS for guidance.
Do not ride, charge, open, modify, or attempt to repair a product or battery that may be unsafe.
16. Limitation of Implied Warranties
To the extent permitted by applicable law, any implied warranties, including the implied warranties of merchantability and fitness for a particular purpose, are limited in duration to the applicable written warranty period stated for the covered component.
Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.
17. Limitation of Incidental or Consequential Damages
To the extent permitted by applicable law, SYKERUNS is not liable for incidental or consequential damages arising from a covered product defect, including loss of use, lost income, substitute transportation, storage charges, or other indirect losses.
Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above exclusion or limitation may not apply to you.
Nothing in this warranty excludes or limits liability that cannot legally be excluded or limited.
18. State Law Rights
This warranty gives you specific legal rights, and you may also have other rights that vary from state to state.
Nothing in this warranty limits rights or remedies that cannot be waived under applicable federal, state, or local law.
19. Relationship to Other SYKERUNS Policies
Shipping damage reported immediately after delivery is handled under the Shipping & Delivery Policy and Return & Refund Policy. Manufacturing defects that arise during the applicable component warranty period are handled under this limited warranty.
